| 摘 要： | 基于采用对称翼型的小展弦比三角形机翼模型,对其在亚音速状态和超音速状态时的升力特性、阻力特性、升阻比特性、稳定性特性进行了理论计算分析。并针对该模型进行数值模拟,分析其超音速流场特性,与理论分析结果进行对比,发现相差不大。得出结论:该翼型机翼在飞机巡航速度为Ma=2时气动性能较好。

| Abstract: | Based on the low aspect ratio delta wing model with symmetrical airfoil,theoretical calculation and analysis are made regarding its lift,drag,lift-drag ratio and stability characteristics at subsonic and supersonic speed.Numerical simulation of this mode is carried out to analyze the characteristics of its supersonic flow field.The comparison with the theoretical analysis results shows that the difference was not significant.The aerodynamic performance of this airfoil is betterwhen the cruising speed of the aircraft isMa=2. |
